Mixed brushes combine the advantages of both materials at a very affordable price. The foam material ensures gentle washing, while the polyethylene bristles perfectly clean up the difficult recesses with established dirt. *BrushTec recommends fixing mixed brushes especially at the bottom of the wash machine (up to the washing height of 30-40 cm). In this zone, the brushes are exposed to the greatest wear and this type of brush is best. However, you can use mixed brushes for the whole wash machine. The average life of the brushes is 30 000 washing cycles.
